SIGNAL. I

Specification of Letters Patent.

Patented Feb. 3, 1914.

Application filed February 13 1909, Serial No. 477,700. Renewed April 19; 1911. Serial No. 622,131.

To all whom it may concern:

Be it known that I, LEVI W. YAGGY, a citizen of the United States, residing at Pasadena, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Signals, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to signals and is especially designed to audibly indicate barometric changes, as upon the gong or bell of an ordinary clock.

In the drawings which illustrate an embodiment of my invention, Figure 1 is a view showing an arrangement of parts whereby the principles of my invention may be realized; Fig. 2 is a detail view of the gong, hammer, muffler and barometer of Fig. 1; Fig. 3 is a side view of the parts of Fig. 1; and Fig. 4 is a view showing a modified arrangement of parts embodying the present invention.

Referring first to Figs. 1, 2 and 3 of the drawings, the reference letter A indicates an ordinary clock, B its gong or bell, and 0 its hammer, all so arranged and disposed that the hammer of the clock will strike hours or fractions thereof as may be the case.

The letter D indicates a barometer which is placed in juxtaposition to the bell B, and in which the hand or indicator E is elon gated sufficiently to extend to a point opposite the opening between the hammer and bell where it carries a muffler F adapted to travel in the path between the bell and hammer. The muffler may be of any suitable material and preferably is a light gauze or other cloth. The hand E is also extended in the opposite direction beyond its pivot and is there provided with a counterweight G adapted to balance the muffler, so that practically no greater power or force is required to carry the muffler than is necessary to move the hand.

The muffler is preferably graduated and in the form shown this is provided by increasing or decreasing the thickness of the material of which it is composed. The path of the muffler being between the hammer and bell as the hand moves, and assuming that the parts are in the position shown in Fig. 1 with the muffler withdrawn from between the bell and hammer when the hand is at one limit of its travel as when the bamuffler correspondingly to interpose an increased muffling surface between the bell and hammer, and finally the thickness of the mufiier may be such as to entirely quiet or muffle the bell when the hand reaches its other limit of movement.

The invention may also be embodied in venous modifications such as will suggest themselves to those skilled in the art, and in Fig. 4 I have shown a modification in which an ordinary Swiss toy weather-indicator is employed. In these instruments when a storm is indicated the figure of a man with an umbrella comes out one door of a house and when clear weather is inclicated the figure of a woman comes out of the other door, the movement of these figures being controlled by a short cord suspended by a weight and which is caused to twist and untwist by variations in the humidity of the air. As shown in Fig. 4 the mufller F is controlled by this cord H and is carried into and out of the space between the hammer and the gong as the cord twists and untwists, the muffler being graduated according to the degree of change that the barometer indicates.

It is of course obvious that the muffler may be arranged in any suitable manner, such for example as reversing its thickness so that when the barometer indicates a storm the muffler will present its thickened portion in the path of the hammer and will gradually reduce the thickness presented to the hammer as the hand moves to its other extreme. It is also to be understood that the muffler may be of any suitable form and material and may be arranged in any suitable manner to accomplish the intended purmay be performed by any other suitable signal device. However, I prefer to associate the others parts With a clockgong, and of course no special construction of clock is required, nor is it necessary to use other than an ordinary barometer having its hand modified as above indicated.

Having described my invention I claim l. A signal device comprising an indicating instrument, an audible signaling means, and a muffler for the signal controlled by the indicating instrument and graduated to affect the signal according to the degree of change of the indicating instrument.

2. A signal device comprising an indicating instrument, a clock-gong and striker, and a graduated mufiier between the gong and striker and moved by the indicating in strument.

8. A signal device comprising a clockgong and striker, an indicating instrument having a hand or pointer, a graduated muiiler of increasing thickness on one end of the hand and adapted to travel in the path between the striker and gong as the hand moves, and a counterweight on the other end of the hand.

In testimony whereof I aflix my signature in presence of tWo Witnesses.
